Abstract

A process for producing a light open-porous mineral insulating board of less than 130 kg/m<3> raw density involves (a) formation of a suspension with a water/solids factor (without foam) of 0.7-1.2 (preferably 0.7-0.9) in an intensive mixer, having a rotating vessel and a rapidly rotating mixing tool, by intensively mixing water with (by wt. of total solids) 40-48% quartz powder ( ≥ 2.5, preferably 3-5 m<2>/g BET specific surface), 15-20% hydrated lime ( ≥ 15 m<2>/g BET specific surface), 25-35% cement, 0.3-0.5% waterproofing agent (preferably silicone oil) and balance additives, the cement/hydrated lime ratio being 1.5-2.3 (preferably 2.0) and the binder content being 45-52 (preferably 50) wt.%; (b) preparation of a foam from water, air and a pore-former with 40-50 kg/m<3> raw density; (c) mixing of the foam into the suspension in the mixer at a lower mixing tool rotation rate for NOTGREATER 120 secs.; (d) pouring of the mixture into a mould and allowing to stiffen to a plastic block with sufficient green strength; (e) vacuum lifting of the block from the mould base and wire cutting of the block into individual boards; and (f) autoclave hardening of the boards.
